Robert Gordon Cousins (January 31, 1859 – June 20, 1933) was an eight-term Republican U.S. Representative from Iowa's 5th congressional district.

He was chosen by the House as one of the managers to conduct the impeachment proceedings of John L. Brown before the Iowa Senate in 1886.

In 1892, Cousins ran as a Republican against Democratic Congressman John Taylor Hamilton, who had won election to the U.S. House seat for Iowa's 5th congressional district two years earlier.

After leaving Congress, Cousins resumed the practice of law in Tipton, and also engaged as a writer and as a Chautauqua lecturer.
